Q7. Function and working of bride rectifire

Ans.

A bridge rectifier is an electronic circuit that converts alternating current (AC) to direct current (DC).

  • A bridge rectifier consists of four diodes arranged in a bridge configuration.

  • It rectifies the AC input voltage by allowing current to flow in only one direction.

  • During the positive half-cycle of the AC input, two diodes conduct and during the negative half-cycle, the other two diodes conduct.

  • This results in a pulsating DC output that is then filtered to obtain a smoother...read more

Q8. Rectifier working in detail

Ans.

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

  • Rectifiers are commonly used in power supplies and electronic devices.

  • They consist of diodes that allow current to flow in only one direction.

  • Half-wave and full-wave rectifiers are two common types of rectifiers.

  • Rectifiers can be used to convert AC power from the mains to DC power for electronic devices.

  • They are also used in battery charging circuits and in converting AC power to...read more

Q9. How working elevator?

Ans.

An elevator works by using a system of pulleys, counterweights, and a motor to move the elevator car up and down within a shaft.

  • Elevators have a motor that drives a pulley system to move the elevator car.

  • Counterweights are used to balance the weight of the elevator car and reduce the load on the motor.

  • Safety mechanisms such as brakes and sensors are in place to ensure safe operation.

  • Elevators are controlled by buttons inside the car and on each floor to select the desired des...read more

Q10. Find the count of request in log file

Ans.

Use a script to count the number of requests in a log file.

  • Read the log file line by line

  • Identify the lines that represent requests

  • Increment a counter for each request line

  • Display the total count of requests

Q11. Find type of requests in log file

Ans.

Identify types of requests in a log file

  • Look for keywords like GET, POST, PUT, DELETE

  • Check for status codes like 200, 404, 500

  • Identify specific endpoints or URLs

Q12. What is ac and dc

Ans.

AC and DC are types of electrical current.

  • AC stands for alternating current and changes direction periodically.

  • DC stands for direct current and flows in one direction only.

  • AC is used in household appliances and power grids while DC is used in batteries and electronic devices.

  • AC voltage can be easily transformed using a transformer while DC voltage cannot be transformed without a converter.

Q13. Operation of solenoid coil

Ans.

The operation of a solenoid coil involves the conversion of electrical energy into mechanical motion.

  • A solenoid coil consists of a wire wound into a tightly packed helix.

  • When an electric current passes through the coil, a magnetic field is generated.

  • This magnetic field attracts or repels a movable ferromagnetic core, resulting in mechanical motion.

  • The direction of the motion depends on the polarity of the current and the design of the solenoid.

  • Solenoid coils are commonly used...read more

Q14. Describe type of electrical motor.

Ans.

An electrical motor is a device that converts electrical energy into mechanical energy.

  • Uses electromagnetic fields to generate motion

  • Common types include DC motors and AC motors

  • Can be classified based on construction (e.g. brushed, brushless) or application (e.g. servo, stepper)

  • Examples: induction motor, synchronous motor, brushed DC motor, brushless DC motor

Q15. Troubleshooting shooting method

Ans.

Troubleshooting shooting method involves identifying and resolving issues in a systematic manner.

  • Start by gathering information about the issue and its symptoms

  • Identify possible causes and narrow down the root cause

  • Develop a plan to address the issue step by step

  • Test solutions and verify if the issue is resolved
